NEPA and Alternative Analysis
Need for Improvements
Existing and future capacity deficiencies:
– Travel demands in the corridor, particularly during peak commuter periods, exceed the
carrying capacity of both the corridor’s roadway system and the current Metrorail Orange
Points of congestion
– Traffic operations are adversely affected by constraints (chokepoints) caused by capacity
or geometric issues.
Limited mode choice
– Service is primarily focused on serving commuter trips to and throughout the region’s
inner core employment areas.
– Geometric deficiencies along the I-66 mainline include short distances between
interchanges which lead to high weaving volumes and absence of shoulders in some
– Travelers experience highly unreliable travel times on I-66 particularly during peak periods.
NEPA Purpose and Need
Improve multimodal mobility along the I-66 corridor by providing diverse
travel choices in a cost-effective manner.
Enhance transportation safety and travel reliability for the public along
the I-66 corridor.
NEPA Study Process / Tiering Approach
• Tier 1 EIS focuses on broad issues
- Purpose and need
- General location of proposed
- Mode / Technology choice
- 10 improvement concepts
• Tier 2 analysis will focus on sitespecific details for selected
Request for Information
The Office of Transportation Public Private
Partnerships (OTP3), in coordination with the Virginia
Department of Transportation (VDOT) and the
Department of Rail and Public Transportation (DRPT),
has issued a Request for Information (RFI).
An RFI is an inquiry only to solicit input from citizens
and private sector on the best practices and
innovative approaches that may be utilized to
address the purpose and need, maximize the
benefits and minimize the costs to citizens of the
No contract or agreement will be entered into as a
result of this process. Information contained in the
responses to the RFI will help OTP3, VDOT and DRPT,
to advance evaluation, planning and development
efforts for the Project, which may result in the launch
of a formal procurement.
Public hearings on Tier 1 Draft EIS were conducted
on March 13 & 14, 2013
Citizen Information Meetings: Early 2014
Citizens can submit their comments and
responses to the RFI on or before November
25, 2013 to the following email address:
Responses to the RFI will be posted on
Project documents, news letters, news
releases, fact sheets and schedule of public
meetings will be posted on Project website.
Additional public involvement opportunities will
be provided if project moves forward to Tier 2
NEPA and potentially a formal procurement.
